The utility model relates to a kind of type type plus-minus method formula and corrects errors from declaring puzzle.

Existing a kind of toy for children, it be on some cubes, stamp respectively numeral " 0,1,2,3 ..., 9 " and sign of operation "+", "-", "=", can various addition formulas of assembled arrangement or subtraction formula with these cubes.This toy structure is simple, and still, whether one often can not to judge this equation to the unfamiliar children of signed magnitude arithmetic(al) correct.Announced " a kind of puzzle " on the utility model patent gazette, its notification number is CN2074481U, it comprises examination question, answer module, module identification mechanism, has identifying hole at two kinds of relative walls of module, and two intermodules are provided with recognizer, the identifying hole degree of depth complementation that module is right, recognizer is provided with the identification pin, and its quantity and arrangement mode are identical with identifying hole, and the examination question module is divided in the two-layer installation test block case, transposition capable of circulation, but the answer module is inserted in the module cartridge of translation.Though it can discern the whether correct of answer, its complex structure.

The purpose of this utility model provides a kind of simple in structure and can discern additive operation or subtraction whether correct type type plus-minus method formula is corrected errors from declaring puzzle.

In order to achieve the above object, the utility model is achieved in that and comprises box body, mobilizable "=" number module that is placed on digital module on the box body, "+" number module, equates with "+" number block length; At the monosymmetric chute that is provided with of the center line of box body, on chute, be equipped with movable sliding block; It is characterized in that: a, be positioned in box body that center line is monosymmetric to be provided with the some conducting blocks that every block length L equates, mutual insulating and fixedly connected between two adjacent conducting blocks is that the conducting block of two symmetries at center is electrically connected with lead with the center line; B, in slide block, be equipped with switch, wherein an end of a switch can with conducting block in a certain be electrically connected, the other end is electrically connected with acousto-optical device one end; Outside in an end that also has a switch and the conducting block a certain is electrically connected, also be electrically connected with luminescent device one end, the other end is electrically connected with an end of power supply; Be electrically connected between the other end of acousto-optical device, power supply and luminescent device; C, on box body, be positioned at position of center line and be provided with the hole, in the hole, be provided with the module that to take out, be fixed with "=" number module and "-" number module that length equates with "+" module respectively in the two sides of module symmetry, this "=" number module lateral distance relative with "-" number module be conducting block length L n doubly, n is a positive integer; The length of d, digital module be conducting block length L m doubly, the m=n+ actual number; The length of e, "+" number module be conducting block length L h doubly, h is a positive integer.During use, as do additive operation, on the hole, place the module that to take out, make to indicate "=" number module up, place digital module and "+" number module on the left side of "=" number module, the digital module that can do answer is placed on the right in "=" number module, moving slider makes the switch connection in the slide block, and is correct as answer, then acousto-optical device is sounded and light, and luminescent device also sends light; Illustrate, as do 2+3=5 addition formula and inscribe, at this moment, the length of " 2 " digital module is (n+2) L, the length of " 3 " digital module is (n+3) L, the length of " 5 " digital module is (n+5) L, the length of "+" number module is hL, "=" on the module in the hole number module is hL with the length of "-" number module, the opposite flank distance is nL between them, because it is symmetrical in center line, indicate therefore that "=" number module is positioned at center line the right and apart from the distance of center line (n/2) L, "=" number module left side is positioned at the length overall of center line module and is like this: L (n+2+n+3+h-n/2) L=(3n/2+h+5); The length on "=" number module the right is: L (n+5+h+n/2) L=(3n/2+h+5); From top two equatioies as can be seen, the distance that therefore is positioned at the center line both sides equates, is electrically connected owing to be positioned at monosymmetric two conducting blocks of center line in box body, like this acousto-optical device, luminescent device energized.Otherwise because asymmetric conducting block mutual insulating, acousto-optical device does not have energized, but the luminescent device energized.

The utility model compared with prior art has following advantage:

1, simple in structure, easy to use;

2, there is not special-purpose power switch, when not using, sounding light not, not power consumption;

3, the accuracy of judgement of correcting errors to the plus-minus method formula is rapid;

4, circuit is simple to only containing acousto-optical device in the box;

5, the corresponding reasoning of imagcs that is suitable for learning children before the order of indicated real figure on the length of digital module and the module.
